'APPARATUS, FOR CONVERTING lVlOTlON.

SPECIFICATION forming part of Letters Patent No. 352,878, dated November16, 1886. A

Application filed April 30, 1886.

To all whom it may concern.-

Be it known that we, JOHN FAYLOOMIs and BYRON EDWARD WING, of Shelby, inthe county of Shelby and State of Iowa, have invented a new and usefulImprovement in Apparatus for Converting Motion, of which the followingis a specification.

Our invention consists in an improved apparatus for convertingreciprocating into rotary motion, as will be hereinafter fullydescribed, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a perspectiveview ofour improved apparatus, showing the same arranged in its operativeposition. Fig. 2 is a perspective dew tail view of one of the hollowflanged disks and the pawl-disk which rotates therein. Fig. 3 is avertical longitudinal sectional view. Fig. 4 is a vertical sectionalview; and Fig. 5 is-a detail View of the adjustable U shaped spring,

- hereinafter described.

The same letters of reference indicate corresponding parts in all thefigures.

Referring to the several parts by letter, A represents the frame whichsupports in their operative positions the various portions of ourimproved apparatus. In'one end of this frame reciprocates between thevertical uprights B the vertical rack-bar O, which we have shown.rigidly secured to the lower end of the vertically-reciprocating rod Dof a windmill, although it is obvious that the toothed racks E mightbesecured to the lower end of the rod D itself, if desired, withoutdeparting from the spirit of our invention.

J ournaled in what we shall denominate the inner end of thesupporting-frame A are two parallel shafts, F F, the inner ends of whichextend on each side of the rack-bar O, and on the inner portions ofthese shafts, but somewhat in advance of the rack-bar, are rigidlysecured the disks G G, having each the thick annular flange H at itsperiphery, against the inner surface of which flange the pawls M bearwhen in operative position. Against the hollow inner face of theseflanged disks G fit the pawl-disks I, which turn loosely on the. innerends of the shafts F, each pawldisk having secured concentrically uponits outer face a pinion, J, which meshes with the teeth of the rack-barC, while the inner face of each Serial No. 200,744.

ner, the wooden shoes Q, which we prefer to.

make of maple, and these maple shoes we pre- .fer to cover with astrip,R, of leather on their outer bearing-edge, although the leather may bedispensed with, if desired, as the maple shoe will work readily withoutit. The inner reduced end of each pawl is formed nearly circular, toadapt it'to fit and turn readily in the inner portion of the flaringrecess L, the outer sides of the flaring recess being farther apart thanthe width of the neck of that end of the pawl, by which arrangement thepawl may turn slightly in the said recess, so as to bring its outerbearing edge into or out of contact with the inner surface of theannular flange H of its disk G, according to the direction in which itspawldisk I is being rotated by the rack-bar, the

flaring jaws of the recesses in the two pawl-;

disks on different sides of the rack-bar being inclined in oppositedirections-on one disk to the right andon the other to the left-so thaton the downs roke of the rack-bar the pawls of one disk will be thrownout into engagement with the flange of its disk, while on the upstrokeof the rack-bar the pawls of the other disk (which on the previousmovement were folded in out of engagement) will in turn be thrown out bythe centrifugal action into contact with the annular flange of its.

disk G, by which arrangement the disks G G are alternately revolved byfriction with the pawls,'one disk on the downstroke and the other on theupstroke of the rack-bar, both disks being thus revolved in the samedirection. This arrangement of the recessesL and the pawls is clearlyillustrated in Fig. 4 of the drawings.

To the outer end of each parallel shaft F is secured a gear-wheel, S,andthese two gearwheels mesh with a flangedpinion, T, secured ontheinner portion of a longitudinal shaft,

II, which carries at. its outer end the large balance drive'wheel V,aronndwhich passes belting to convey the rotary motion to any desiredpoint.

It will be seen that by our improved apparatus a continuous revolutionof the driveshaftis obtained, as the said shaft is rotated both on theup and down stroke of the rackbar, as previously described. By constructing the pawls with the wooden bearing-shoes the pawls are prevented fromwearing smooth and slipping on the inner face of the metal flange of thedisks G, which would be liable to occur if a plain metal pawl wereemployed, and the leather strips R aid still further the gricifitionbetween the pawls and the said flanged is s.

We construct the pumpingrod N of the windmill in two parts, W W, theadjacent ends of the said parts being connected together by theadjustable U shaped spring X, the ends of which are formed with theperforations Y Y, which admit of the spring being adjustably secured tothe said ends or the rod so as to regulate its tension as desired. Itwill be seen that this springserves to takeup part of the motion whenthe windmill is running too fast, thereby equalizing the speed withwhich the lower portion of the rod V7, and therefore the rack-bar, isreciproeated, thereby causing the machinery of our improved apparatusfor converting motion to run moreslnoothly and protecting it from suddenjars and strains, as

will be readily understood.

From the foregoing description, taken in connection with theaccompanying drawings, the construction. operation. and advantages ofouriin proved apparatus for converting motion will be readilyunderstood. The adjustable U-shapcd tension-spring X can be applied toany mill, as it may be moved in or out to regulateits tension asrequired. A con tinuous revolution of the drive-shaft and its band-wheelis secured, the said shaft being rotated on each movement of thepumping-rod of the windmill bothup and down, while by constructing ourimproved pawls with the wooden bearing-shoes the bearing-edges of whichmaybe covered with leather, all danger of the said pawls slipping andbecoming inoperative is effectually obviated.

We propose to -file a separate application for theUshaped spring incombination with a pump rod or equivalent. Having thus described ourinvention, what we claim,and desire to secure by Letters Patent, is-

1. The combination, with the vertically-reciprocating rack bar, of ,thetwo parallel shafts having on their outer ends the gear wheels, andhaving rigidly secured upon them near their inner ends the hollowflangeddisks, the disks turning loosely onthe inner ends of the saidshafts, having on their outer sides the concentric pinions which meshwith the said raclobar, and having on their inner sides the circularenlargements formed with the re cesses having the flaring mouthsarranged as described, the metal pawls having the reduced inner-endsfitting and turning in the said recesses, and formed at their outer endswith the longitudinal recesses, the wooden shoes secured in the saidrecesses, and the drive-shaft having at its inner end the pinion and atits outer end the balance drive-wheel, all constructed and arranged tooperate in the manner and for the purpose herein shown and set forth.

2. The combination,with the hollowflanged longitudinal recesses, thewooden shoes secured in the said recesses, and the leather stripssecured around the bearing-edges of the said shoes, substantially as andfor the purpose shown and described.

3. The combination, with the pumping rod of a windmill, consisting ofthe upper part and the lower part having at its lower end the rack-bar,ot' the adjustable U shaped spring connecting the adjacent ends of thesaid parts together,the two parallel shafts having on their outer endsthe gear-wheel and having rigidly secured npon them near their innerends the hollow flanged disks, the disks turning loosely onthe innerends of the said shafts,

having on theirouter sides the concentric pin ions which mesh with thesaid rack'bar, and having on their inner sides the circular enlargementsformed with the recesses having the flaring mouths arranged asdescribed, the metal pawls having the reduced inner ends fitting andturning in the said recesses, and formed at their outer ends with thelongitudinal recesses, the wooden shoes secured in the saidrecesses, andthe drive-shaft having atits inner end the pinion and at its outer endthe balancedrive-wheel, all constructed and arranged as and for thepurpose shown and described.
